Private PracticeDr Allan Harkness, Consultant Cardiologist

I am a Consultant Cardiologist in Colchester, Essex. I see patient from across Essex and Suffolk. My private practice is at:

The Oaks, Colchester

Nash Basildon at The Essex Cardiothoracic Centre, Basildon.

My practice covers the whole spectrum of adult cardiology including chest pain, breathlessness, heart failure, high blood pressure, murmurs, blackouts and palpitations. My comprehensive training in Glasgow and London resulted in accreditation in both Cardiology and General Medicine. I can therefore offer a more holistic review when considering problems relating to your heart.


I have been a Consultant Cardiologist at Colchester Hospital since 2006 and at the Essex Cardiothoracic Centre since it opened in 2007.

In April 2010, I became the Clinical Lead for Cardiology at Colchester Hospital. I have led the introduction of many advances in cardiology services, including valve clinics, heart failure services, MRI compatible pacemakers, stress echo, transoesophageal echo, 3D echo and CT coronary angiography. I am accredited in echocardiography with the British Society of Echocardiography and in CT Angiography with the British Society of Cardiovascular Imaging.

In 2016, I forged new links between Colchester and Ipswich Hospital’s cardiac services and provide specialist cardiac imaging for Ipswich Hospital.

In May 2017, I became Clinical Director for Specialist Medicine at Colchester Hospital and then in October I became the Divisional Director for Medicine and Emergency Care. I am passionate about improving patient safety and constantly look to improve both my practice and the standards of care of my department – for instance by introducing safety checklists. This is reflected in my patient feedback. I am an active member of the education committee of the British Society of Echocardiography, contributing to guideline development, training programmes and I wrote the BSE Android App – EchoCalc.

I have helped develop close links with primary care through mentorship of GPs and nurses with a special interest in cardiology. I also took the lead in developing the ACE community heart failure service.
